The right size for a circle

A seller in Abu Dhabi joins an online forum for people who run small shops. It has several hundred members. She assumes that with so many people in one place, it must be where the good ideas are.

Mostly it is not. The posts scroll past too fast to read. The same questions come up every week. Anyone with something genuinely new keeps it quiet, because sharing it with hundreds of competitors feels like giving it away.

It is tempting to believe that more people means more breakthroughs. More minds, more chances. Up to a point that is true. Two sellers comparing notes will run out of ideas long before twenty do.

But follow the logic to its end and it falls apart. A group of ten thousand is not a hundred times wiser than a group of a hundred. Past a certain size, every new member adds noise faster than insight.

What actually produces the new idea is something else. A handful of people who trust each other enough to say what is really working. Enough breathing room in their weeks to try something that might fail. And a shared expectation that each of them will come back next month having tested something, not just having read about it.

That is why the most useful circle she finds is likely to be eight people meeting once a month, not the crowd on her screen. The places and groups that keep producing new things tend to have the right conditions, not the largest numbers.

There is a size that works. It is rarely the biggest one on offer.
